A pneumatic tire is disclosed having two annular bead portions having a bead core. A carcass extends between the bead portions through sidewall portions and a tread portion, wherein the carcass includes at least two axially inner plies which extend down from the tread and axially inward of the bead core, said at least two axially inner plies being wound around the bead core forming respective turn-ups, each turnup being located axially outward of the bead core. The carcass further includes a first axially outer ply which extends down from the tread towards the bead core and positioned axially outward of the bead core, wherein at least one of the axially outer plies is formed from reinforcements having a higher break strength than the reinforcements of the axially inner plies.

Aircraft tire

A pneumatic tire having a carcass and a belt reinforcing structure wherein the belt reinforcing structure is a composite belt structure having at least one radially inner spiral layer and at least one zigzag belt reinforcing structure located radially outward of said spiral layer. The zigzag belt width is preferably wider than the spiral layer.

A pneumatic radial aircraft tire is described having a B/A ranging between 60-70%, wherein B is the width of the tire between the wheel flange, and A is the inflated tire width under rated pressure. The tire may further optionally include a tire bead portion having a Ra/Fr1 relationship which ranges from about 1 to about 2.1, wherein: Ra is the tire heel radius at uninflated and in an new and unused condition, and Fr1 is the wheel flange elliptical radius at the heel section of the tire. The tire may further optionally include a SW/TS ratio which ranges from about 0.1 to about 0.5, wherein SW is the chafer gauge at area A, TS is the total sidewall rubber gauge at area A, wherein A is defined as the region in the sidewall that has a lower radial endpoint defined by the point of contact between the flange and the tire at inflated, unloaded condition, and an upper radial endpoint Ah defined by the tire wheel flange point of contact when the tire is at inflated, and at 100% rated load.
